LEON BERGER BY ATTORNEY 3,977,192 Patented Feb. 12, 1963 Fine 3,077,192 INTERCHANGEABLE DISC FOR SURGICAL DRAWAGE DEVBCE Leon Eerger, 148--23 Edgewood Stu, Rosedale, NX. Filed Feb. 1, 1962, Ser. No. 170,405 2 Claims. (Cl. 128-285) This invention relates to the art of surgical drainage devices.

According to the invention there is provided an im proved support for a drainage bag assembly including a shallow cup-shaped member provided with a flange adapted to engage the rim of an opening in the dramage bag. A resilient annular disk may be removably inserted in the cup-shaped member to overlay the body of the wearer. The disk has an opening which is axially aligned with an opening in the wearers body. The disk may be made of sponge rubber or a variety of other materials, and may have a smooth or grooved face. The cup-shaped member may be formed of rubber and may be integrally molded with the drainage bag. A flexible stiffener ring may be embedded in the cup-shaped member. This ring may have hooks extending outwardly of the member for engaging ends of a strap.

A principal object of the invention is to provide a surgical appliance adapted to effect drainage of a body opening with greater comfort to the wearer thereof, greater protection to the lining of the body opening, improved sanitation, etc.

A further object is to provide a drainage bag assembly for a colostomy opening or the like, in which the assembly is adapted to support resilient pressure disks of various types.

Another object is to provide a novel cup-shaped support for a resilient pressure pad, the support having a flexible flange engageable with a rim of an opening in a drainage bag.

For further comprehension of the invention, and of the objects and advantages thereof, reference will be had to the following description and accompanying drawings, and to the appended claims in which the various novel features of the invention are more particularly set forth.

In the accompanying drawings forming a material part of this disclosure:

FIG. 1 is a side elevational View of an assembly embodying the invention.

FIG. 2 is a longitudinal sectional view taken on line 2-2 of FIG. 1.

FIG. 3 is an exploded perspective view of parts of the assembly.

FIG. 4 is a perspective view of a resilient ring employed in the assembly.

FIG. 5 is a perspective view of part of a drainage bag.

FIG. 6 is a sectional view taken on line 66 of FIG. 3.

FIG.

FIG. FIG. 7.

FIGS. 9 and 10 are sectional views similar to FIG. 8 of other resilient disks.

FIG. 11 is a perspective view of another drainage appliance according to the invention.

FIG. 12 and FIG. 13 are sectional views taken on lines 12-42 and 1313, respectively, of FlG. 11.

Referring first to FiGS. 1 and 2, there is shown a surgical appliance assembly 26 including a flexible rubber or plastic bag 22 having opposed walls 21, 23. This bag may have a closed or open narrow lower tubular end 24. If the bottom end 24 is open, it may be closed by a suitable clamp (not shown). The upper or wider 7 is a perspective view of a resilient disk.

8 is a sectional view taken on line 8--8 of end 26 of wall 21 of the bag is formed with a round hole 25, best shown in FIGS. 2 and 5. Detachably engaged with the bag is a dished support member 30. This member has an annular flange 28 formed at the rear thereof and defining a groove 27 with the annular back 32 of the support member. The rim of hole 25 can be stretched to fit over the flange and into the groove 27 so that the bag is removably supported on the support member 30. Embedded in the back 32 of the support member is a fiat springy metal ring 34, best shown in FIGS. 2 and 4. This ring stitfens the back 32 of the support member. Diametrally opposed extensions are formed at opposite edges of the ring. These extensions are bent to form hooks 38 adapted to engage ends of a strap S shown in dotted lines in FIG. 1. The strap may extend around the wearers body to secure the appliance assembly thereon.

The support member 39 has a forwardly extending cylindrical flange 37 which defines a shallow dished recess R with the forward side of the back 32 of member 30; see FIGS. 2 and 3. In this dished recess removably fits an annular disk 4% having a central hole 4-1 somewhat smaller than central hole 39 in member 30. This hole aligns with drainage hole H formed in the wearers body B as indicated in FIG. 2.

The disk 44 is made of soft sponge rubber and its forward face F extends outwardly of the free edge of flange 38 since the disk 46 is thicker than the depth of the dished recess R.

The assembly of bag 22, support member 30 and disk 40 provides a comfortable, sanitary, surgical drainage appliance for draining waste from the body opening H. The resilient disk it) conforms in shape to curved or irregular body contours. Instead of forming the disk 40 of sponge rubber, it may be made of flexible solid rubber or plastic; it may have a putty-like viscous mass; it may be a mass of fibrous material such as cotton; or one or more layers may be made of porous paper or cellulose.

In FIGS. 7 and 8 the disk 40 is shown made of plastic. The disk 46 of FIG. 9 is made of solid resilient rubber. The disk 4% of FIG. 10 is made of a plurality of layers 43 of fibrous material secured to each other by adhesive. The front surface F of disk ill may be flat. Alternatively, the surface may be curved convex or concave. Surface F of disk 449* shown in FIG. 9 is concave and is coated with a pressure sensitive tacky, adhesive layer 42 which insures that the disk is held securely and prevented from lateral movement when the tacky layer is placed against the skin of the wearers body.

Disk 46 is formed with an annular groove G in which a suitable viscous medicament or ointment may be placed for therapeutic purposes.

Regardless of the consistency of the mass of the annular disk, it will conform to the contour of the wearers body around hole H to prevent leakage of liquids. The disk can readily be removed from the dished recess and replaced with another when required.

In FIGS. 11-13 is shown another assembly 20 in which the upper part 26 of bag 22* is integrally formed with the support member Sii at annular back 32 of the dished recess R. Ring 34 is embedded in the back 32 In other respects the assembly 20* is similar to assembly Ell and corresponding parts are identically numbered. Disk 4% or one of the equivalent disks Mi -46 may be removably inserted in the recess R for the same sanitary, sealing purposes as described above.

While I have illustrated and described the preferred embodiments of my invention, it is to be understood that I do not limit myself to the precise constructions herein disclosed and that various changes and modifications may be made within the scope of the invention as defined in I the appended claims.
